Neither of those errors are specific to GDE, but it looks like the issue is with your theme (or possibly a conflict between your theme and something else). Perhaps the theme is loading its own copy of jquery instead of using the version provided with WordPress? And perhaps the version in use is also not the same between the two?

I’m only guessing on this, but it’s been known to happen (especially if you just updated to WordPress 3.5, which has an upgraded jQuery library). I would reach out to the theme developer, or momentarily switch themes just to confirm if it’s the source of the problem. Possibly you’ll be able to activate your plugins with that other theme installed and then switch back to the theme you want, and not suffer incompatibilities. But again, that’s just a theory on my part.
